Choose sheets of paper for the pages of your book, not too many if you just like me are a beginner. All your pages don't necessary have to be white, try mixing in old newpapers for example. I used two pages from a 1950's French Elle and a small paperbag...

Vik pappersarken på mitten och placera dem i varandra.

Fold your paper sheets at the middle and place them inside each other.

Use one of your paper sheets as a template and mark where you want holes to stitch it all together. The more holes you make, the more sturdy it will be, but also more time consuming. I decided that five holes was enough for me. Use a needle to make holes through your template and all the other book pages, a few paper sheets at a time is easiest. Make sure to place your holes evenly through all the pages of your book.

You will most likely discover that the pages of your book are not of the same length (or is 'width' more correct?) now. That happens when you fold them at the middle and put them all together. You can use a small knife to correct it, or simply decide that you like it just the way it is.
